I'm rather embarrassed to admit how our "accident" happened. But in the name of science, here we go! I had taken some rock out of the tank to do some rearranging (to move his favorite hiding place to the front area so we could see him) I had taken his rock out and set it in a bucket, for about 1 minute. I then put the rock back in the tank, and went about cleaning up. About 30 minutes later, I got to thinking that I had not checked the bucket to make sure he hadn't come out of the rock. So (in the dark) I stick my hand in the bucket. He had come out into the bucket, and was obviously very glad to see me, because he firmly attached himself to my arm,and started crawling up. Now I'M not really squeamish, but that was a totally new deal for me, and in my haste to separate the two of us, I fear that I may have been a little freaked out. I was trying to be gentle, but I was also trying to get the lid on the tank unsealed (I use a heavy tape around the lid). Some time during the fracus, and after I got him back in the water, I noticed that I still had this 6" leg still crawling up my arm. It had come off right next to his body. It was difficult to see exactly where it had come off for a while because he didnt come out to play for about 3 days. I dont think I got that rough, and now,I dont feel quite as bad, because I really do think that he may have released it himself. I will try to get a picture of the new appendage and post it!
